10 Another object of the invention is to provide a wrenchA having a substantially U-v shaped rod carrying the movable jaw and also providing a handle.

A further obj ect of the invention is to provide a wrench wherein the nut is formed with Y a thread of such pitch that, after the movable jaw is initially shifted to clamp the work between the jaws, a substantially half turn of said nut will serve to bindthe jaws inv engagement with the work.

Other objects of the invention not specifically mentioned in the foregoing will appear during the course of the Afollowing description.

In the accompanying drawings:

Figure 1 is a sectional view of the device showing the teeth of the worm nut in engagement with the teeth of the handle,

Figure 2 is a fragmentary side elevation showing the flattened side of the worm nut disposed to confront the teeth of the handle,

Figure 3 is a fragmentary sectional view on the line 3-3 of Figure 2 looking in the direction indicated by the arrows.

In carrying the invention into effect, I employ a preferably steel rod 1 which is bent into substantially U-shape to provide parallelvlegs 2 and 3.v The leg 3 is notched at the inner side of its upper end portion to provide a rack 4. Slidably mounted on the legs 2 and 3 is a movable jaw 5 provided with a flat gripping face 6. Formed on the jaw 5 and depending from the lower wall thereofis a sleeve 7 slidably surrounding the rod 2, said sleeve having a threaded lower end portion 8.

Rotatably mounted on the sleeve 7 is a worm nut 9 having a thread 10 for engagement with the teeth of the rack 4. The worm nut is provided with a flattened side V1l. Screwed on the threaded portion of said sleeve :is a 'nut 12 j providing ai stop shoulder i ifor the worm 9. l

rissociatedv with the` movable `fixed jaw 13 having a fiat grippingface'14.

The upper end portions of the le0s2 and 31.55

are reduced to .provide stop shoulders 15 for said Iixed jaw 13,*and theredu'ced portions l extend through the jawv and are upset as at 16. The fixed jaw is thus rigidly secured in position.

In use, the xed jaw 13 is brought into contactwith one side of the work and the movable jaw 5 engaged with the opposite side thereof. The latter mentioned operation is accomplished by rotating thev worm nut 9 until the flattened side 11 thereof is disposed to confront the teeth 4, thus disengaging the wormr nut from the teeth. The jaw 5 may then be moved into position. The worm nut is then again rotated to engage the thread thereof with the rack 4 and advance the movable jaw, and iti-s to be noted that the pitch of the thread of theV worm nut is such that substantially half a turn of said nut will serve to bind the work between the jaws. The work may then be moved as desired. When it is desired to release the jaw 5, the worm 9 is rotated in an opposite direction until the flattened side 11 confronts the rack 4, thus permitting the j awto be retracted and the wrench disengaged from the work.

I-Iaving thu-s `described the invention, I claim: l

1. A wrenchfincluding a rod bent to provide a handle having spaced legs, a lixed jaw rigidly connecting the free ends of said legs, a movable jaw slidably mounted on the legs to coact withthe fixed jaw and provided with Va sleeve slidably surrounding one of said legs, teeth formed on the other .o f said legs, and a nut rotatably mounted on said sleeve to VcoactV with said teeth 'for shifting Y the movable jaw, the nut being provided with able jaw may be quickly shifted. Y 2. A device of thecharacter described including a U-shaped handle having spaced Aa portion to clearl the teethfwhereby the movdepending sleeve freely receiving one of the legs therethrough, teeth on the other of said legs, and a nut rotatably mounted on said sleeve and provided with a thread to engage s said teeth whereby the nut may be rotated for shifting the movable jaw, said thread being of a pitch such that substantially a half turn of the nut will advance the movable jaw sufciently to bind the work between the 10 jaws after the jaws have been initially shifted to engage the work. Y Y -Y 1 3. A device of the character described including a lixedj aw, a rod connected thereto and formingl a handle "provided with spaced l legs, a movable jaw slidably monnte'd on theV legs and having a'sleeve formed integrally therewith, said sleeve receiving one of the legs therethrough and providingV an Velongated'bearing for the movable jaw, teeth on ,20 the other of said legs, and a nut rotatably :mounted on said sleeve to coact with said teeth for shifting the movable jaw.

In testimony whereof I ailfix my signature.
